Hi,
Could you send me (off-list) the CPIN file in question? Also, I'm sure
that the CPOUT files are probably too large, but could you try to send
even a portion of them? In addition, maybe send the topology and
restart file as well. Any additional information (AmberTools/cpptraj
version etc) will be helpful. Thanks,
-Dan
